Abstract
A mechanism is provided for fabricating a thermally assisted magnetoresistive random access memory device. A bottom thermal barrier is formed on a bottom contact. A magnetic tunnel junction is formed on the bottom thermal barrier. The magnetic tunnel junction includes a top ferromagnetic layer formed on a tunnel barrier. The tunnel barrier is formed on a bottom ferromagnetic layer. A top thermal barrier is formed on the top ferromagnetic layer. A top contact is formed on the top thermal barrier. The top contact is reduced to a first diameter. The tunnel barrier and the bottom ferromagnetic layer each have a second diameter. The first diameter of the top contact is smaller than the second diameter.
